Abstract

The study of fluid flow in porous media is relevant to many applications such as oil and gas production, Underground Gas Storage (UGS), Underground Hydrogen Storage (UHS), CO2 Storage or Sequestration, and enhanced Geothermal Systems. The parametrization adopted for representing the multi-phase flow behavior at the macroscale is strongly related to the parametrization at the microscale/pore scale. Therefore, understanding and characterizing pore scale phenomena is fundamental. This work is dedicated to the investigation and application of the Lattice Boltzmann method (LBM) as a tool for the simulation of two phases-flow in porous media at the microscale, with a particular focus on the numerical schemes and the initial and boundary conditions that have to be defined to properly represent imbibition and drainage processes characterizing underground fluids storage activities. A 2D porous domain, replicating a physical micromodel used for two-phase flow experiments is simulated using an open-source parallel library with the aim of reproducing laboratory experimental thermodynamic conditions and, when the model is validated, extending the simulation to reservoir thermodynamic conditions and corresponding fluids properties. Part of this work involves the evaluation and selection of the most suitable LBM approach for representing the displacement processes occurring in occurring during underground storage scenarios. The proposed tests analyze the two-phase flow phenomena for hydrogen, carbon dioxide, and methane in the presence of reservoir formation water.
